Cecilia Rouse, chair of the White House Council of Economic Advisers, told CNBC on Friday that the Biden administration is worried that Russia's invasion of Ukraine will cause famine in parts of the world.

The bread basket for many parts of the world is served by Russia and Ukraine, as the two countries are major producers of wheat, soybeans and other agricultural products.

The war is making it difficult to plant and export key crops. The problem is compounded by higher energy and fertilizer prices.

The international aid agencies are working with us to make sure there is some humanitarian aid.

After two years of disruptions related to the coronaviruses, food prices have increased due to the war in Ukraine. The global health crisis is believed to have caused an increase in the number of people who are hungry.

According to the World Food Programme, Russia and Ukraine are responsible for most of the wheat imported to East Africa.

13 million people in the Horn of Africa were severely hungry before Russia invaded Ukraine, according to the UN. According to the UN, the area is facing a serious drought that has affected crops and killed livestock in countries such as Ethiopia.
